Multiple issues since updating to 3.19.xx

No changes have been made to any existing set up for N1MM prior these software crashes..Now when I set up in N1MM for SO2R CW, which I have done many times, when I change radios, using the \ key and try to transmit on VFO B, Smart SDR crashes. All the slices are set up appropriately, OTSRP is set up by the book.The only way to get things going again is to close out SSDR and reboot the radio. This happened twice in the first hour of the recent IARU contest. After that I abandoned SO2R. I just recreated this problem a few minutes ago.

Second Issue.

This afternoon, I was watcing the FT8 Screen on 6m as stations where decoded, watching for needed grids. That went on for 10-20 minutes, then suddenly the decocding stopped and no data (audio) was being received by the software. Again, all I/O channels are the same as they've been for months. Its the same problem in MSHV and JTDX, so it's a radio problem. The DAX channels are on 1, as they've always been.

Lastly,

I use the Maestro when contesting and very consistently, it will be up for 45 minutes or an hour and then abruptly shut down. The batter is full bars and green. I have to reboot it.

As usual, I've tried everything I know to try to solve these issues, but right now, I have no clue. While it might be anecdotal, these problems started after I upgraded to 3.19.

So as I sit here, I can't do SO2R or decode FT8 with my 6600M.

Any help is appreciated.
